New 3-D gas density maps of NaI and CaII interstellar absorption within 300pc
Barry Y. Welsh, Rosine Lallement, Jean-Luc Vergely +1
We present new high resolution (R>50,000) absorption measurements of the NaI doublet (5889 - 5895A) along 482 nearby sight-lines, in addition to 807 new measurements of the CaII K…
Properties of the Diffuse X-ray Background toward MBM20 with Suzaku
A. Gupta, M. Galeazzi, D. Koutroumpa +2
We used Suzaku observations of the molecular cloud MBM20 and a low neutral hydrogen column density region nearby to separate and characterize the foreground and background diffuse…
High resolution NaI and CaII absorption observations towards M13, M15 and M33
B. Y. Welsh, J. M. Wheatley, R. Lallement
We present high resolution (R = 60,000) measurements of the NaI D1 and D2 (5890 A) and CaII K (3933 A) interstellar absorption line profiles recorded towards several post-AGB stars…
